In this comment, I revisit the question raised in Karadja and Prawitz (2019) concerning a causal relationship between mass emigration and long-run political outcomes. I discuss a number of potential problems with their instrumental variable analysis. First, there are at least three reasons why their instrument violates the exclusion restriction: (i) failing to control for internal migration, (ii) insufficient control for confounders correlated with their instrument, and (iii) emigration…

A Crash Course in Good and Bad Controls
Many students, especially in econometrics, express frustration with the way a problem known as “bad control” is evaded, if not mishandled, in the traditional literature. The problem arises when the
Blunt Instruments: Avoiding Common Pitfalls in Identifying the Causes of Economic Growth
Concern has intensified in recent years that many instrumental variables used in widely-cited growth regressions may be invalid, weak, or both. Attempts to remedy this general problem remain
A Practical Guide to Weak Instruments
We provide a simple survey of the literature on weak instruments, aimed at giving practical advice to applied researchers. It is well-known that 2SLS has poor properties if instruments are exogenous
Weak Instruments in IV Regression : Theory and Practice
When instruments are weakly correlated with endogenous regressors, conventional methods for instrumental variables estimation and inference become unreliable. A large literature in econometrics
Estimating the Impacts of Program Benefits: Using Instrumental Variables with Underreported and Imputed Data
Abstract Survey nonresponse has risen in recent years, which has increased the share of imputed and underreported values found on commonly used data sets. While this trend has been well documented
What Do We Learn from the Weather? The New Climate-Economy Literature
A rapidly growing body of research applies panel methods to examine how temperature, precipitation, and windstorms influence economic outcomes. These studies focus on changes in weather realizations
Does Compulsory School Attendance Affect Schooling and Earnings?
We establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws. Individuals born in the beginning of the year start
